SPECIFICATION forming ea of Letters Patent 754,773 ,aawi1 March '15, 1904'.

Application filed Jul 's, 1903. semi No.- 164,111. on modeh) To a whom it may concern:

Be it known thatI, FRANooIs J As, engineer, a subject of the Queen of the Netherlands, and a resident of Paris, in the Republic of France, have invented new and useful Improvements Relating to Apparatus for the Purification'of Gas, which improvements are fully set forth in the following specification.

- Coal-gas at the generating works is submitthe gas a pressure greater than that which it previously had. By the employment of this novel apparatus it is possible to effect an economy of fifty per cent. in the consumption of gas.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved apparatus, and Fig. 2 represents a vertical transverse section of the same taken on line A B of Fig. 1.

Similar characters of reference indicate corresponding parts.

The apparatus consists, broadly, of a cylinder a, closed at its extremities and divided by a partition I) into two unequal compartments 6 and 0. The compartment 6, which is the larger of the two, is traversed by a longitudinal shaft p, capable of rotation, and around which are wound four coils 1, 2, 3, and 4, the convolutions of which are arranged side by side in three superposed 'rows. At the left-hand extremity of the apparatus the four coils 1, 2, 3, and 4 open into the compartment 6. Their apertures h it it" 11' are diametrically opposite. Assuming for a moment that the chamber contains Water up to a certain level, it will be obvious that the apertures h h h h will alternately come into contact, owing to their 5 rotation with the shaft 10, with the water or with the gassituatedabove it, which gas enters the apparatus through the. socket 0. Each coilwill therefore take up alternately a certain quantity of water'and a certain quantity of gas. These fluid and liquidbeads or sections will pass ,through the coils first of all in the outer row from left to right, owing 2, 3, and- 4, the convolutions of which are inclined in the invers'edirection, andfinally inthe central row 1", 2",3, and 4" from left to right again. The fluid andliquidjbeads or sections, thepressure of which increases in proportion as they progress through the apparatus, will finally pass into the socket o, constituting a hollow portion of the shaft 10 and communicating with the compartment 0. The movement of the shaftp may be produced by means of a motor of any convenient kind driving the shaft either directly or by the intermediary of transmission-gear.

The compartments 6 and 0 may be caused to communicate one with the other at certain times by the intermediary of a chamber j, arranged-beneath the cylinder, and two holes is Z, formed in the cylinder-wall. Of these the hole k is obturated by a valve m, while the hole Z is-free. The hole is assures communication between the compartment 0 and the chamber 1', while the hole Z places the said chamber in communication with the compartment 6.

In order to start the apparatus, water is introduced into the compartment I) through the cock n, which may be surmounted by a funnel. the cock at is closed, whereupon the cock 0 for the introduction of gas coming from the meter is opened and the apparatus is placed in movement. The phenomena described above are produced and the purification of the gas is perfect, owing to the extremely vigorous mixing and the gradually-increasing pressure of the gas and the liquid. From the compartment 0 the completely-purified gas proceeds to the utilization appliances through the conduit p. The water charged with the impurities falls upon an inclined plane or plate g, from which it flows to the bottom of When the water reaches the level w y,

- impurities contained in the washing-water, it

is desirable to renew it. In order to effect this,a drain-cock s on the chamber jis opened and the dirty water flows out. The apparatus is again filled up to the level as y by means of the cock n, as described above.

The apparatus represented in the accompanying drawings comprises three rows of coils; but this is not essential, and it should be understood that the dimensions of the apparatus and the number of coils should be proportioned to the quantity of gas consumed by the installation to which this purifying apparatus is adapted.

I claim as new and desire to secure by Letters Patent 1. An apparatus for the purification of gas, consisting of a cylindrical vessel closed at either end andprovided with a transverse partition dividing the same into two compartments, a shaft in one of said compartments hollow atone end and journaled in the partition and in one endof the vessel, and a plurality of pipes wound spirally around said shaft and rotatable with the same having their open ends diametrically the farthest distance from the shaft and their otherends terminating in the hollow end of the shaft for discharging their contents into the other compartment,

hollow at one end and journaled in the partition and in one end of the vessel, a plurality of pipes wound spirally around said shaft and rotatable with the same, having their open ends diametrically the farthest distance from the shaft and their other ends terminating in the hollow end of the shaft for discharging their contents into the other compartments, an inclined plate in said last-named compartment below the discharge end of the shaft, a chamber connecting the compartments for returning the liquid from the last-named compartment to the compartment containing the pipes, anda valve for said chamber, substantially as set forth. i

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
